Nutrition Supplements

Choose topic:


Health and well-being after gastric bypass is achievable if a person carefully follows  nutritional diet. However, in addition to healthy eating plan, a properly-balanced dietary supplements are also required since absorption of numerous vitamins and minerals is reduced.

The risk of dietary insufficiency

Dietary insufficiency is not diagnosed in somewhere around 50% of individuals who undergo gastric bypass surgical treatment. Some doctors reveal even more nutritional deficiencies along with typical complications that can arise. Increased awareness of the possible side effects of nutritional insufficiency after gastric bypass may guide doctors as well as patients for more effective identification and treatment.

Individuals after gastric bypass, gastric sleeve or gastric band are especially vulnerable to malabsorption of iron, B vitamins, calcium and vitamin A because the major sites of absorption consisting of the duodenum (a part of the small intestine that links to the stomach) and a diverse segment of upper jejunum (the middle part of the small intestine) are bypassed. Furthermore, gastric acid release from the small pouch is limited and absorption of iron, vitamin B12, calcium and folic acid is severely reduced because of pouch achlorhydria.

Additionally, malabsorption of these micronutrients may happen when food which goes into the proximal small bowel is not chewed carefully or is not enough warmed up. Digestive enzymes are also inadequate in the small gastric pouch.

Some patients have mentioned mental exhaustion causing difficulties in studying and focusing which may be partly associated with reduced absorption of B vitamins. Some other micronutrients are absorbed along the entire length of the small intestine.

Nutritional supplements

To prevent such additional complications, nutritional supplementation usually starts immediately after surgical treatment is performed, while the patient is still in the medical centre. On the other hand, negative side effects can develop several weeks or even months after the surgery. For instance, patients may not be compliant with consuming recommended dietary supplements or doctors may become less diligent concerning the  monitoring for nutritional insufficiency. A study identified that 3 years after gastric bypass surgical treatment, despite having multivitamin dietary supplements, up to 50% of patients had experienced iron deficit, while nearly 30% had cobalamin insufficiency.

The recommended dietary allowance (RDA) focuses on the protection of nutritional insufficiency, but it does not determine optimal intakes for an individual and his unique nutritional requirements occurring after gastric surgery. A significant amount of scientific analysis shows that the optimal level for many vitamins and minerals may possibly be much greater than present RDA.

You need to get the following dietary supplements on a regular basis to avoid nutritional deficiencies. Make sure you keep in mind that all supplements must be smashed or simply reduced in to six to eight tiny bits because right after gastric bypass you are not capable to digest entire capsules and it can also be challenging for the tablets to go via your completely new anatomy.


Get a higher-potency daily chewable multivitamin pill as well as mineral dietary supplement that consists of a minimum of 17 mg of iron, 420-400 mg of folic acid, selenium, copper and zinc.

Calcium Supplement

Take 1000 to 1800 mg of calcium on a daily basis to avoid calcium deficiency and also bone disease. To boost absorption get the calcium in two to three separated dosage amounts during the day. For example, 600 to 500 mg three times a day. Calcium citrate is the recommended form of calcium supplement.

Vitamin D Supplement

Take a total of 700 to 1,000 international units (IUs) of vitamin D each day. The total amount should be taken in separated doses of 410 to 500 IUs two times a day. Vitamin D should be consumed with your calcium supplement. If you want, you can take a formula calcium-vitamin D dietary supplement to evade taking numerous tablets, so long as it consists of the appropriate dosages.

Vitamin B12 Supplement

Take 500 mcg of vitamin B on daily basis. It can be taken as a pill, or even in sublingual versions placed under the tongue.

Other Supplements

Some patients require additional folic acid or even iron supplements, especially women who are still productive age. Your dietitian will talk about this with you.
